I don’t understand how can one seduce you into love?

What you can try is not to love the fantasy or love the feeling of excitement but love a person for human qualities they possessed. You wanted to marry that other man because you fell something. Whatever that something was wasn’t based in reality. Why would you want to marry someone who drinks does drugs doesn’t work and steal from you? That’s the last person you should get engaged to. Clearly desire to marry that unsuitable partner wasn’t based on reality.

Try not to base your feelings for this man on chemistry or how he looks at you but rather on what kind of person he is?

Listen, we all love to love. Not just Libras. Lol I’ve never even heard that love is Libras trademark. In fact people born in all 12 months love to love. It’s everyone’s trademark. Don’t put too much trust into “I do this because that’s who I am”. Use logic. We all love to love. You can fall in love with wrong person of course like many others, but use logic not to end up entangled with wrong people. Figure out who the person is before making big decisions

You cannot stop love but you can stop yourself from making big choices such as moving in with them or spending money on them or marrying them before you know for sure if they are suitable partners etc
